8. Touch your toes 够脚趾头

If you're bored of sit-ups, try this exercise instead. Lie on the floor with arms straight up, pointing at the ceiling. Slowly curl yourself up and forward so that your hands are pointing towards your toes--and if you can, touch your toes. Then return to your starting position but do it slowly to stretch the muscles. Repeat 15-20 times.

如果你厌烦了做仰卧起坐，试试这个练习。躺在地板上，双臂垂直上举指向天花板。慢慢把自己抬起来，这样你的手就越来越靠近脚趾——如果你能够，就够到脚趾好了。然后恢复到开始的姿势。但是一定要慢慢做，以便充分地伸展你的肌肉。重复做15-20次。
